Dear [Sales Rep].
Thank you for reaching out regarding the potential seven-figure deal with [well-known brand]. I appreciate the opportunity and understand the importance of closing this deal.
However, I must respectfully push back on the request for several customizations with their in-house software in a few weeks time. While I understand the potential benefits of closing this deal, I must consider the risk associated with consuming the entire team's resources and sacrificing key roadmap progress for all of our other clients.
I understand that these customizations are important to [well-known brand), but I also want to ensure that we are able to maintain a balance between meeting the needs of our clients and maintaining the integrity and stability of our enterprise-grade ERP software.
As an alternative, I would suggest that we explore options such as:
I would be happy to schedule a meeting to discuss these options and find a mutually beneficial solution.
Thank you for your understanding and please let me know if you have any further questions.
Best,
[Your name]
